What is the proportion of male orange tabbies to female orange tabbies?
Seems that approximately two thirds of orange cats are male, and only one third of orange cats are female. http://www.catchow.com/catcarecenter_physical3.aspx?combinedID=21035 Red in cats is a sex-linked color, carried on the X gene. Therefore, a male cat whose X carries red will be a red tabby. A female cat who carries one red and one non-red X will be a patched tabby, a tortoiseshell, or a calico (if she also has the dominant gene for white markings). A female cat who is homozygous for red (has it on both X genes) will be a red tabby. This is why you see more male red tabbies than females.
